Abstract

The present invention is an improvement of trampoline net structure including a frame in circular ring form provided with multiply downward foot trusses and a sheet unit within the frame. The sheet unit includes a net 5 element and a skirt element that both are connected by a connecting unit while the net element is connected with the frame by multiply elastic units. The improvement further includes multiply bar units that each of them as positioned at the frame with a top end connected with a top surface of the skirt element. Because the net element and the frame are thoroughly segregated 10 by the skirt element, a user will not fall into a clearance between the net element and the frame when jumping on the net element so as to prevent the accident and injury

Description

TITLE: IMPROVEMENT OF TRAMPOLINE NET STRUCTURE (a) Technical Field of the Invention The present invention is related to an improvement of trampoline net 5 structure, particularly an improvement of trampoline that is able to thoroughly segregate a frame and a sheet unit of a trampoline so as to prevent an user from injury because of falling off the trampoline. (b) Description of the Prior Art A trampoline of the prior art basically consists of a frame in circular or 10 rectangle form, which is peripherally provided with multiply foot trusses at its bottom circumference in order to stand on a floor, and a net unit positioned at a center of the trampoline that an outer circumference of the net unit is connected to an inner circumference of the frame through multiply sets of spring or elastic unit. When a force is applied onto the net unit, it will 15 deform along a normal axis with respect to its surface at a downward displacement. When the force disappears, the multiply sets of spring or elastic unit will provide a recovery recoil because of the deformation caused by the downward displacement for restoring the net unit upward till its original position. Therefore the user can keep jumping up and down repeatedly on 20 the net unit in order to achieve the exercise effect. However, the trampoline 2 of the prior art is not provided with a safety device and the user will possibly be injured from falling into a clearance between the frame and the net unit when the user has not acquired a mature skill or an accident takes place. Thus the trampoline of the prior art is not sufficiently safe in operation. 5 Further the trampoline of the prior art can be provided with a security net at an outer periphery in order to prevent the user from falling out. However such security net is only positioned at the outer periphery of the trampoline of the prior art that cannot resolve the above-mentioned deficiency and thus does not have adequate protection. Resolving the above-mentioned deficiency is 10 the objective of the present invention.

3 SUMMARY OF THE INVENTION The present invention is to provide an improvement of trampoline net structure including a frame in circular ring form provided with multiply downward foot trusses and a sheet unit within the frame. The sheet unit 5 includes a net element and a skirt element that both are connected by a connecting unit while the net element is connected with the frame by multiply elastic units. The improvement of trampoline net structure of the present invention further includes multiply bar units that each of them as positioned at the frame with a top end connected with a top surface of the skirt element. 10 Because the net element and the frame are thoroughly segregated by the skirt element, a user will not fall into a clearance between the net element and the frame when jumping on the net element so as to prevent the accident and injury. An objective of the present invention an improvement of trampoline net 15 structure is to enhance the protection of the skirt element with a multiply directional absorbing function in order to prevent the user from injury and falling out. The other objective of the present invention an improvement of trampoline net structure is to resolve the frequent damage due to the stress concentration at the connection joint of net structure of the trampoline of the 20 prior art.

4 BRIEF DESCRIPTION OF THE DRAWINGS FIG 1 is a three-dimensional perspective diagram illustrating a preferred embodiment of the present invention. FIG 2 is a localized magnification diagram of Fig. 1. 5 FIG 3 is a three-dimensional disassembly diagram of Fig. 2. FIG 4 is a localized magnification diagram illustrating a preferred embodiment of the present invention.

5 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Firstly please refer Fig. 1 through Fig. 3 illustrating a preferred embodiment of an improvement of trampoline net structure 1 that includes a frame 10 in circular ring form, a sheet unit 20, a connecting unit 30, an elastic 5 unit 40 and a plurality of bar unit 50. The frame 10 is provided with a plurality of foot truss 11 extended downward. The sheet unit 20 is provided with a net element 21 with a circumference provided with a plurality of attaching element 211 and a skirt element 22. 10 The connecting unit 30 further includes a first connector 31 and a second connector 32 that the first connector 31 is peripherally positioned at a top surface of the net element 21 and the second connector 32 is positioned at a bottom surface of the skirt element 22. The net element 21 connected with the skirt element 22 by the connecting unit 30, which is a zip in this preferred 15 embodiment. Each elastic unit 40 has one end connected with each of the plurality of attaching element 211, which is peripherally positioned at a circumference of the net element 21, and the other end connected with the frame 10. Namely both ends of the elastic unit 40 is respectively connected with the frame 10 and 20 the attaching element 211.

6 Each bar unit 50 is positioned at the frame 10 and a top end of each bar unit 50 is connected with a top surface of the skirt element 22. Thereby the sheet unit 20 of the embodiment of the improvement of trampoline net structure 1 can thoroughly segregate the net element 21 and the 5 frame 10 so that an user will not be injured from accident of falling into a clearance between the net element 21 and the frame 10 when exercises on the net element 21. The safety of trampoline exercise is therefore enhanced and then the improved trampoline is more suitable for young children playing.
